People report enjoying momentary extraverted behavior, and this does not seem to depend on trait levels of introversion-extraversion. Assuming that introverts desire enjoyment, this finding raises the question, why do introverts not act extraverted more often? This research explored a novel explanation, that trait introverts make an affective forecasting error, underpredicting the hedonic benefits of extraverted behavior. Study 1 (n = 97) found that trait introverts forecast less activated positive and pleasant affect and more negative and self-conscious affect (compared to extraverts) when asked to imagine acting extraverted, but not introverted, across a variety of hypothetical situations. Studies 2-5 (combined n = 495) found similar results using a between-subjects approach and laboratory situations. We replicated findings that people enjoy acting extraverted and that this does not depend on disposition. Accordingly, the personality differences in affective forecasts represent errors. In these studies, introverts tended to be less accurate, particularly by overestimating the negative affect and self-consciousness associated with their extraverted behavior. This may explain why introverts do not act extraverted more often (i.e., they overestimate hedonic costs that do not actually materialize) and have implications for understanding, and potentially trying to change, introverts' characteristically lower levels of happiness.

Is self-critical perfectionism an antecedent of depressive symptoms, a consequence of depressive symptoms, or both? In the present study, self-critical perfectionism (i.e., harsh criticism of one's actions, negative reactions to perceived failures, and extreme concerns over others' evaluations) and depressive symptoms were conceptualised as a unified, interlocking syndrome wherein self-critical perfectionism and depressive symptoms reciprocally influence each other over time. This reciprocal relations model was tested in 240 undergraduates studied using a four-wave, 4-week longitudinal design. As hypothesised, reciprocal relations were observed between self-critical perfectionism and depressive symptoms, with self-critical perfectionism predicting changes in depressive symptoms and vice versa. Results suggest persons high in self-critical perfectionism may find themselves entangled in an escalating pattern where self-critical perfectionism both leads to, and results from, depressive symptoms. Research focused exclusively on unidirectional relations between self-critical perfectionism and depressive symptoms may ignore information critical to accurately understanding self-critical perfectionism, depressive symptoms, and their interrelation. Instead of assuming unidirectional relations between self-critical perfectionism and depressive symptoms, researchers are encouraged to test for reciprocal relations between these two variables.

Multidimensional perfectionism is related to grandiose narcissism, with other-oriented perfectionism showing the strongest, most consistent relationships. The relationships with vulnerable narcissism, however, are unclear. Our study investigated how three forms of perfectionism-self-oriented, other-oriented, and socially prescribed perfectionism oriented perfectionism appears to represent a form of perfectionism predominantly related to narcissistic grandiosity, whereas socially prescribed perfectionism is predominantly related to narcissistic vulnerability. As the first study to examine perfectionism in relation to narcissistic grandiosity and vulnerability, our research both extends and clarifies the nomological network of the perfectionism construct in important ways.
